Thank you for those who replied to me off-list. Encouraged by some working examples, I retried the investigation, and now I figured out what was wrong with my setup. The motherboard seems to be checking for some terminal escape sequences. At first I was working on FreeBSD console (TERM=cons25), and that was the cause of failure. Then I tried it from xterm, and it successfully started to redirect. But that was not the end of the story ;-p With xterm I could get console messages redirected, but I couldn't enter the BIOS setup menus. It was not reading the "DEL" key that I typed. So then I changed to screen (ports/misc/screen), and finally I can enter the BIOS menues and all. So to summarize, when I work inside screen, both tip and kermit worked well with the config shown above. cu -s 115200 -l /dev/cuaa0 also worked well. I was also sugested with minicom, but that I could not configure well to get everything working (it has many features and I didn't look into it that much). I still cannot enter the Intel NIC's setup menu, which is initiated with Ctrl-S. And for 3ware RAID BIOS (entered with Alt-3), the menu is entered (as verified on video console), but the output is not redirected to the serial port, though, the keys I type on the serial side are sent and recoganized by the RAID BIOS. But I'd say those are another story, and I'm happy that I can fiddle with the main BIOS setup for now. Thank you very much for your help. -- Hiroharu Tamaru
